Apple IIe Card - Manual (Page 102)

You use the Apple IIe Option Panel to adjust some aspects of the
Apple IIe Card’s operation. Most of the adjustments are made in the
General Controls panel, the panel that appears automatically whenever
you open the Option Panel.
Most of the settings in the General Controls panel take effect
immediately and remain active whenever you start up the IIe Startup
program, until you change them again.
You can change the processing speed of the Apple IIe Card. The Option
Panel provides two Speed settings: normal and fast. The Normal setting
represents the normal processing speed for an Apple IIe computer. The
Fast setting is up to twice as fast as the Normal setting. (The actual speed
varies among programs, depending on a number of factors—principally,
the amount of graphics processing a program requires.)
Depending on the type of program you’re running, you may benefit from
changing the Speed setting. For instance, a spreadsheet program would
benefit from the added processing speed by performing calculations
more quickly. Other programs, however, may be less effective running
under the Fast setting. For instance, many games may run too quickly.
And programs that require precise time-interval measurements—such as
music programs— may need the normal Apple IIe processing speed to
run properly.
If you’re uncertain what Speed setting is most appropriate for the
program you want to run, try the Fast setting first. If the program doesn’t
run as expected, change the setting back to Normal.
